Purchased on a trip to WDW, took the tags off, aaaaand.... it didn't fit our dog. This is brand new but no tags. Disney Parks Sulley Monsters Inc Fuzzy Spirit Jersey for Dogs (or a large cat!). It is so cute and super comfy! Please see size chart in one of the photos and learn from my mistake. No returns for sizing issues, sorry.
